I'm visiting Japan in April and I'm applying to go watch Gaki no Tsukai being filmed live! I'm wondering if anyone has tried (whether successful or not) and if you have, do you have any tips? I know there's an online form, but I'm going to try by sending in postcards to "stand out". I've read a couple of guides on what to do when sending an application, but most are extremely outdated.

What is the exact procedure? What was it like going to the studio? Any other comments?

Yeah, there doesn't seem to be any audience for many of the gaki episodes in recent years...although slightly bigger scale episodes like for example, the Grand Prix series(Anger King GP, Surprised-face King GP,etc) do have audiences.

There are audiences that for other shows, like Downtown DX. I've read that DT still does some free-talk for the live audience in DT DX that are not broadcast(although compilation DVDs were released of these free-talks).
